It uses a copper core center electrode that increases conductivity and improves heat control, which helps the plug wear evenly over its service life. The design is engineered to resist overheating under heavy engine loads, a common stress point for marine outboards that run at sustained high RPM. Champion built this plug to resist fouling and to provide superior corrosion resistance, both important in the wet, salt-exposed environment outboard engines operate in.\u003c\/p\u003e\u003cp\u003eThis plug carries Champion's own plug number 312 and is cataloged for Evinrude outboard engines. It delivers dependable, proven performance and is a straightforward drop-in replacement when your outboard's plugs are due for service. The copper core construction is the same technology used across Champion's marine plug lineup, chosen for its reliable spark delivery and resistance to fouling in two-stroke and four-stroke outboard applications.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Champion\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e CCH312\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChampion Plug Number:\u003c\/strong\u003e 312\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug Designation:\u003c\/strong\u003e L87YC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore Material:\u003c\/strong\u003e Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e Regular Metric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 037551000357\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Equivalent Part Number:\u003c\/strong\u003e CHA312\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Application:\u003c\/strong\u003e Evinrude outboard engines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis spark plug is cataloged for use in Evinrude outboard engines.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eCHA312\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Champion L87YC spark plug fit?\u003c\/strong\u003e The Champion L87YC, plug number 312, is cataloged for Evinrude outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs CCH312 the same as Champion plug number 312?\u003c\/strong\u003e Yes, CCH312 is the part number for the Champion L87YC marine spark plug, which Champion identifies as plug number 312.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the OEM equivalent for the Champion L87YC?\u003c\/strong\u003e CHA312 is the OEM equivalent part number for the Champion L87YC (plug number 312) spark plug.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the electrode material in this spark plug?\u003c\/strong\u003e The Champion L87YC uses a copper core center electrode, which increases conductivity and gives more precise control over heat range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this spark plug weigh?\u003c\/strong\u003e The Champion L87YC (CCH312) weighs 0.15 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this plug resist corrosion in a marine environment?\u003c\/strong\u003e Yes, the Champion L87YC is built with superior corrosion resistance, which matters for outboard engines exposed to moisture and salt air.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this spark plug resist fouling during normal use?\u003c\/strong\u003e The Champion L87YC is designed to resist fouling, one of the traits Champion built into this marine plug line.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Champion L87YC an OEM or aftermarket spark plug?\u003c\/strong\u003e The Champion L87YC (CCH312) is a Champion-branded OEM replacement plug, not a generic aftermarket copy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this spark plug handle heavy engine loads?\u003c\/strong\u003e The copper core design of the Champion L87YC is engineered to resist overheating under heavy engine loads, which is common in sustained high-RPM outboard use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does the Champion L87YC use?\u003c\/strong\u003e The Champion L87YC (plug number 312) has a regular metric thread size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many spark plugs come with this listing?\u003c\/strong\u003e This listing is for the Champion L87YC spark plug, part number CCH312.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the L87YC compare to other Champion marine plugs?\u003c\/strong\u003e The L87YC (plug number 312) shares the same copper core electrode technology used across Champion's marine spark plug lineup, differing mainly in the specific engine application it is cataloged for.\u003c\/p\u003e","brand":"Champion Spark Plugs","offers":[{"title":"Default Title","offer_id":49027462627547,"sku":"CHA-L87YC","price":3.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/L87YC__99278.1739459029.500.750_b3427666-9dd5-4cbb-aa46-ffde8c9b79cd.jpg?v=1785329074","url":"https:\/\/www.goodvibesmarina.com\/products\/champion-l87yc-marine-spark-plug-for-evinrude-outboards-copper-core-plug-number-312","provider":"Good Vibes Marina","version":"1.0","type":"link"}
